Anyone could please help me figure out what´s causing this? Brown/burned? Leaf
I feed them water PH (6-7)
BioBizz BioGrow (3ml/L) and recently switched to the combo of BioBloo(1ml/L) m + BioGrow (2ml/L) since they are just starting to flower.
If it's only on the topmost leaves, I'd guess your lamp is a little too close - raise it 5-10cm and it'll be fine (with my lamp, this happens if it's closer than 25cm from the top leaves, but it will depend of the lamp)
